Mind-control technology has taken society by a storm, a multiplayer on-line game called "Slayers" allows players to control human prisoners in mass-scale. Simon (Lerman) controls Kable (Butler), the online champion of the game. Kable's ultimate challenge becomes regaining his identity and independence by defeating the game's mastermind (Hall).
In a future mind-controlling game, death row convicts are forced to battle in a 'Doom'-type environment. Convict Kable, controlled by Simon, a skilled teenage gamer, must survive thirty sessions in order to be set free.
